Professor Jon Agar asks why scientists say they ask ‘why?’, and traces the curious history of the idea of curiosity-driven science; as he explores the curious place of curiosity in the history of science. He was awarded the 2016 Wilkins-Bernal-Medawar Medal in recognition of his work as a leading figure in the history and philosophy of science. His ground breaking research covers issues including military technology, the origins of computing, astronomy, surveillance, and public engagement with science. The lecture was recorded on April 4 2017 at the Royal Society. For more events like this, see our schedule - ow.ly/KhTi306gT
